This elegant chicken in horseradish and chervil sauce is a sophisticated take on a comforting classic. By gently poaching a whole chicken with aromatic vegetables, you create a succulent base and a deeply flavoured stock that forms the heart of the dish. The addition of earthy Jerusalem artichokes and anise-scented fennel provides a wonderful texture, while the freshly grated horseradish offers a gentle heat that cuts beautifully through the rich double cream.
As a high-protein main course, this recipe is both nourishing and deeply satisfying, making it an excellent choice for a Sunday family lunch or a restorative midweek meal. The delicate, liquorice-like notes of the fresh chervil finish the sauce with a bright, herbal lift. Serve this dish alongside simple boiled potatoes to soak up every drop of the creamy, peppery gravy.

Ingredients for Chicken in Horseradish and Chervil Sauce
1 whole chicken
1 small whole onion
1 carrot
3 bay leaves
1 tablespoon peppercorns
1 tablespoon coarse salt
4 teaspoons butter
450g Jerusalem artichokes, peeled and sliced
1 fennel bulb, sliced
1 tablespoon plain flour
6 tablespoons freshly grated horseradish
180ml double cream
60ml chopped chervil
Salt and pepper
900g boiled potatoes
How to make Chicken in Horseradish and Chervil Sauce
Back to contentsPut the chicken in a large casserole with the onion, carrot, bay leaves, peppercorns, and salt. Add enough water to cover the chicken, then bring to a boil and simmer for 1 hour, or until the meat is white. Carefully lift the chicken from the broth and let cool. Strain the broth and save 600ml for the sauce.
Make the sauce. Melt the butter in a large pan. Add the sliced artichokes and fennel and cook for 2 minutes. Sprinkle the flour over the vegetables and stir until the flour and butter have combined. Pour in half the reserved chicken broth and stir until smooth. Add the remaining chicken broth and the horseradish and bring to a boil. Add the cream and salt and pepper and return the sauce to a boil, then decrease the heat to a simmer.
Remove the skin and bones from the chicken. Break the meat into medium-size pieces. Stir the chicken and chervil into the sauce and let it simmer for a couple of minutes, or until the chicken is heated through. Season with salt and pepper and serve with boiled potatoes.
